Electroacoustics Toolbox updated to 3.8.3

Electroacoustic’s Toolbox 3.8.3 can now be downloaded from the Mac App Store and from FaberAcoustical.com.

New in version 3.8.3:

  • An issue with channel sensitivity adjustments in the Meter Bridge and Sound Level Meter tools has been addressed.
  • When loading Room Analyzer tools from a project file, if a permissions error occurs for an audio file being used for analysis, an Open dialog will be presented with the file in question selected. Once the file is then manually loaded via the dialog, the permissions will be properly set for the next time the project is loaded. This is an issue with sandboxed copies of Electroacoustics Toolbox downloaded from the Mac App Store.
  • The Room Analyzer tool’s plotting is more reliable when loading the tool from a project file on recent versions of Mac OS X.

SignalScope Pro for Mac has also been updated with the same improvement to the Meter Bridge and Level Meter tools.

RoomScope 4 with additional hardware support is now available for download

RoomScope 4.0 is now available for download on the App Store.

As with the recent update to IOScope, RoomScope now supports fractional octave band smoothing of 2Ch FR magnitude and coherence data (1/6, 1/12, and 1/24 octave bandwidths). RoomScope also adds built in support for iTestMic and iAudioInterface2 from Studio Six Digital and support for automatic downloading of sensitivity and frequency response data for the Dayton UMM-6 USB measurement microphone.

Other improvements to RoomScope include the following:

– RoomScope 4 employs a new plotting framework for real-time data graphs and high resolution image export.

– A bar graph is now used to display room acoustics parameters across octave or 1/3-octave frequency bands.

– Support for drawing directly to an external screen (from iPad) has been removed in favor of screen mirroring, which is handled by iOS.

– Audio hardware input and output options are now presented from a separate toolbar button, which looks like a microphone, on iPad, iPhone 6 and iPhone 6 Plus.

– It is possible to adjust the line thickness of plotted data.

Faber Mac apps are all 64-bit, built for Yosemite

This week, all Faber apps for Mac OS received updates to improve their compatibility with Yosemite (Mac OS 10.10). Electroacoustics Toolbox 3.7, SignalScope Pro 3.7, SignalScope 3.7 and SignalSuite 4.7 are all 64-bit applications that have been built for Yosemite.

The Room Analyzer tool, available for in-app purchase in Electroacoustics Toolbox, now calculates room parameters in whole or 1/3-octave frequency bands from impulse response data that has been sampled at higher sample rates (88.2, 96, 176.4, and 192 kHz), in addition to sample rates of 44.1 and 48 kHz that were supported previously.

The Octave Analyzer tool, found in both Electroacoustics Toolbox and SignalScope Pro, also now supports the higher sample rates for real-time spectral analysis of input signals in whole or 1/3-octave frequency bands.

The Dual FFT Analyzer (only in Electroacoustics Toolbox) and FFT Analyzer tools now support additional dB vertical scale factors of 3, 6, 9, 12, 15, or 18 dB per division in the graphic display.

Various bugs and potential instabilities in each app have been corrected.

These new apps all require Mac OS version 10.7 or later.

Trial versions of each app may be downloaded from FaberAcoustical.com.

RoomScope 2.1 validates reverberation time measurements

In version 2.1, RoomScope now presents a nonlinearity parameter to offer additional guidance on the validity of each acoustic decay parameter (T20, T30, T60, EDT). Values of greater than 10 ‰ (per mille, or parts per thousand) indicate that the estimated reverberation or decay time may be suspect, or that integration limits may need to be adjusted manually to obtain a more accurate result.

RoomScope 2.1 is now available for download on the App Store.

Electroacoustics Toolbox 3.5 adds AppleScript support for room acoustics

Version 3.5 of Electroacoustics Toolbox extends AppleScript support to the Room Analyzer tool (sold separately), which enables automated room acoustics analysis and data retrieval via AppleScript. Now, in addition to automating the acquisition of impulse response data, users can employ AppleScript to control the analysis of that data to extract relevant room acoustics parameters.

With increased automation capabilities, the Room Analyzer tool also now takes additional steps to verify the accuracy of acoustic decay time estimates, including T20, T30, T60, and EDT. For each of these parameters a nonlinearity value (in per mille, or parts per thousand) indicates how close the acoustic decay approaches a straight line, which is the basic assumption in reverberation time estimation. A nonlinearity value greater than 10 suggests that the user might want to take a closer look at the data to determine whether adjustments must be made to the integration limits for the decay curve to get a more accurate measurement.

Version 3.5 also addresses some issues, which include the following:

– Room acoustics parameters are properly plotted across 1/3-octave bands in the Room Analyzer tool.

– Radio buttons are properly deselected in the IR source drawer of the Room Analyzer tool when switching between Dual FFT or Oscilloscope measurements.

A bug has been addressed that could prevent the “Try” buttons in the project window from successfully opening a trial of the Noise Dosimeter or Room Analyzer tool.

RoomScope Updated for iOS 7

RoomScope version 2.0 now fully supports iOS 7 with a refreshed look and feel that is consistent with recent updates to SignalScope Pro and IOScope. Although RoomScope still supports iOS 6, its appearance remains largely the same as before on the older iOS.

What’s new in RoomScope 2.0?

– RoomScope’s appearance has been completely revamped for iOS 7. RoomScope supports both iOS 6 and iOS 7, but looks largely the same on iOS 6 as the previous version.
– Audio data handling is more efficient.
– When entering a preferred sample rate, “48k” can be entered in the text box, as an alternative to typing out “48000.”
– Default input sensitivities have been updated, based on measurements of the iPhone 5S and 5C microphones and headset inputs. Nominal input sensitivities have also been updated for iPad Air and iPad mini with Retina display.
– Cursor info text now uses a larger font.
– 2Ch IR works properly when the internal excitation signal is selected for the X input and pan is set to 100%.
– A bug in the HTTP file server has been fixed.

RoomScope is a universal app designed for iPad, iPhone, and iPod touch.

RoomScope 1.6 automatically finds the end of the decay

In version 1.6, RoomScope’s Room Analyzer tool now estimates the optimal end point for the decay curve–that is, the point at which the acoustic decay meets the noise floor in the impulse response data. This allows the Room Analyzer to provide better reverberation time estimates without the need for the user to manually adjust the decay curve limits with the built-in cursors. Decay curve limits can still be set manually, as before.

RoomScope now loads IR data from CSV, MAT, and TXT files

In version 1.5, RoomScope’s Room Analyzer tool can now load impulse response data from csv, txt, and MAT files saved within the app. Any csv, txt, or MAT files which contain time domain data, and are created by Faber Acoustical’s other iOS apps are also supported. Data files created in other Faber apps, such as SignalScope Pro or IOScope, would need to be added to RoomScope via iTunes File Sharing.

RoomScope 1.5 is available for download on the App Store.

Pop those balloons with RoomScope 1.3

A common request for RoomScope has been to directly capture room impulse response (IR) data using impulsive noise sources, such as balloons or starter pistols. RoomScope 1.3 now supports both single-channel and dual-channel IR data acquisition. The dual-channel capability has been built-in since version 1.0 of RoomScope, enabling the use of an omnidirectional loudspeaker and various excitation signals including broadband noise and frequency sweeps. The new single-channel IR acquisition tool can capture IR data directly by popping a balloon or firing a starter pistol within an acoustic space of interest. The input signal can be triggered in order to automatically begin data acquisition when the instantaneous input level crosses a user-defined threshold.

It should be noted that single channel analysis doesn’t mean that only one channel of data can be captured at one time. In fact, with an iPad and a multi-channel USB audio interface, it is possible to capture IR data from multiple microphones simultaneously (obviously, the mics and supporting cables, adapters, etc, would also be needed). Single channel analysis simply means that each input channel is treated independently from all other input channels. In contrast, dual-channel analysis means that a single measurement is based on data acquired from two input channels (using auto and cross-spectral analysis).

RoomScope 1.3 is now available for download on the App Store.
